IMPROVEMENT IN DUMMY-LOCOMOTlVE TRUCKS.

` Specification forming part of Letters Patent No. 43,208, dated June 21, 1864.

['0 all whom it may concern:

Be it known that we, ISAAC L. HILT and A. V. W. RAUsoH, both of Frankford, in the county of Philadelphia and. State ot' Pennsylvania, have invented certain new and useful- Improyements in Dummy-Locomotives and f Steam-Railway Gars;y and we do hereby declare that the following is a full, clear, and exact description thereof, whi-h will enable persons skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Y ,Figure l is a longitudinal vertical section of a steam-railway car. Fig. 2 is a plan ot' thev engineand running-gear. Fig. 3 is a plan'of a portion ot' one of the driving-axles and section ofthe cog wheel which is fitted thereon.

Similar letters of reference indicate corresponding parts. This invention consists in certain improvements in the running-gear of dummy-locomotives and steam-railway cars, whereby greater facility is-aftbrded for turning curves, and the driving-power is applied to' trucks at both ends of the locomotive or car, and the body ofthe car is relieved from all jarring otherwise caused by the engines and their attachments. y 4

A A'are two independenttour-wheel trucks, arranged one at each end of the locomotive or car, and supported on their axles B C and B G', in the usual manner. D is along supporting-frame, of iron or wood,connecting the two trucks A and A', and supporting the carbody E, the boiler G, and the engines H Il. This frame has rigidly connected with it, in positions over the two axles B B', which are both driving-axles, two pedestals, II', which are supported upon and fitted to journals a a, provided on the hubs of two driving cogwheels, J J', which are arranged one upon each ofthe two driving-axles B B'. The upper parts of these pedestals are made in the form of upright pivots, which are ntted to bearings provided for them in the transoms b b of the trucks, and so serve to connect the two trucks with the frame D, and which are also received in sockets e e, secured firmly to the bottom of the car-body E, for the purpose of retaining the body of the carin its proper position relatively to the frameD and the trucks. The body E, may also be supi ported upon the trucks by friction-rollers o other means which will prevent it from interferin g with the free swinging or turning movements of the trucks. The frame D does not extend rearward beyond the front or driving axle B' of the rear truck A, but extends forward beyond the rear or driving axle B 0I" the forward truck and over the front axle C of the lat-ter, and in order to `support the boiler and cylinders of the engine, which are at the front end of the said frame, which overhan gs the axle U, the said frame is also supported upon the latter axle by means ot' boxes f f, which rest upon the said axle, andthe backs of which are grooved, as shown in Fig. 5, to fit the lower edges ofthe frame in such manner that they maybe prevented from moving laterally in the said frame, but permitted to :nove lon gitudinally thereto as the trucks turn in running over curves, in which operation the axle G moves lengthwise within the said boxes.

Theengine-pistons are connected with cranks g g upon a counter-shaft, K, arranged in fixed bearings upon the frame D, and geared by a pinion, It, with the cog-wheel J upon the forward drivin g-axle B. The cranks g g are also connected by long coupling-rods t' i with two cranks, g g', on a counter-shaft, K, which is arranged on bearings inthe rear portion of the frame D, and which is geared by a pinion, h', similar to h, with the cog-wheel J' of vthe rear driving-shaft B'. The rods t' i are also connected at the middle of their length with cranks g2 g2 on a third counter-shaft arranged in suitable bearings on the frame DI at the middle of its length. Ihe object of'this third counter-shaft and cranks is to stiiit'en and strengthen the rods 'i t'. The said shaft is furnished with a fly-wheel, L, which helps the cranks over their centers and equalizesl their motion. The pinions h and h' are rigidly Vsecured upon their respective counter-shafts; but in order to provide for their respective cog-wheels J and J' remaining in gear with them as the trucks swing or vibrate aboutthe pivots ofthe pedestals I I' in turning curves, the said cog-wheels must be free to oscillate upon their respective axles, as shown in red and blue outlines in Fig. Thisoscillation is provided for by enlarging the portion of each axle which is received within the hub of the wheel, as shown at a in Figs. 1 and 3, so that the form of its longitudinal section is that of a circle described from the center of the axle and its transverse section issquare. The opening provided in the center of the wheel for the reception of the axle is square, and of the same size all the way through, as the largest part of the swell fn of the axle. The cog-wheels are held in their places on the swells ofthe axles by their broad hubs p p, fitting into openings in the pedestals I l', as shown in Fig. 4, and while so heldinplace are kept parallel with the frame D, and in line with their respective pinions whatever position the trucks and axles may assume With reference to the frame D in turning curves. The cogs of the wheels J J should be slightly rounded on their faces.

What we claim as our invention, and desire to secure by Letters Patent, is-.-

1. The two independent trucks A A, pivoted to and combined with the supportingframe D by means of pedestals I l", which are arranged directly over one of the axles ofeach truck, and which serve at the same time as a means of transferring the weight of the said frame to the axles, substantially as herein specied.

2. The two pedestals I I', constructed with pivot-like heads to enter sockets e e, attached to the bottom of the car-body, and thereby keep the body in place upon the supportingframeD ot the engine and driving mechanism, substantially as herein described,as well as pivot the said frame to the trucks.

3. The combination ofthe two counter-shafts K K', one constituting the crank-shaft of the engine and theother coupledwith itby cranks and connecting-rods, and one geared with one of the axles of one ofv the independent trucks and the other gearing with one of the axles ofthe other of said trucks, for the purpose of applying power to axles of both trucks, substantially as herein specified.

4. The intermediate counter-shaft, K2, and its cranks g2 g2, applied in combination with the counter-shaft K K and connecting-rods it', substantially and for the purpose herein specified.

5. The sliding boxesff, applied in combination with the frame D'and forward axle of the forward truck to slide longitudinally upon the said frame and allow the axle to slide within them, thereby providing for the support of a portion of the weight of the boiler and heavy parts of the engine upon the said axle while providing for the vibration of the truck, substantially as herein described.

6. Keeping the cog-wheels of the drivingaxles inline with the frame D, and the pinions of the counter-shafts by so fitting them to their respective axles that they are free to oscillate laterally thereon, and tting their' hubs to openingsin the pedestals I I', or their equivalents, substantially as herein specified.
